pythonbrew isn’t getting picked up by by mod_wsgi file, config follows:
import os
import sys
import site
site.addsitedir('/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages')
sys.path.append ('/home/bharal/public_html/dumpstown')
os.environ['DJANGO_SETTINGS_MODULE'] = 'dumpstown.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
and the pythonbrew version of python i want to use is situated here:
/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages
and my pythonbrew install is here:
/home/bharal/.pythonbrew/
How do i tell mod_wsgi to use this version (2.7.2) and not the default python version that shipped with ubuntu (2.6)?
When i run my server, i get errors like so:

as you can see from the logs, the server is still looking at python 2.6!! Why? I’ve kicked off pythonbrew so when i type in python i can see the version is 2.7.2, and all the settings and packages i need are importable!
UPDATE as indicated in the answer below, the mod_wsgi doesn’t care which python i tell it to use – in fact, i cannot tell it to use any particular python. The only way to do so is to download an uncompiled wsgi file, compile with the particular python version i want, and use the compiled wsgi.
See my other question Error: Command failed with rc=65536 python and mod_wsgi for some of the steps and links to tutes if you like. In the end i didn’t compile against 2.7 (my 2.6 was fine and it was too hard to get the pythonbrew compile working)
That particular error has nothing to do with the version of Python used. Use:
sys.path.append (‘/home/bharal/public_html’)
sys.path.append (‘/home/bharal/public_html/dumpstown’)
To get mod_wsgi to use a specific version, compile it from source code against that version or find a binary package for mod_wsgi compiled against the correct version.
